Do staffs get along with guinea pigs?
I don't think you can generlise with breeds, all dogs are
individuals.
I have a staffy bull that was brought up with other animals, I
had 2 cats when she was a puppy she used to lay by the fire with
them.
I now have guinea pigs in open topped C&C cages and she is
absolutely brilliant with them.
Ofcourse this may not apply to ALL staffordshire bull terriers.
It depends how they were treated from puppies.
